Convert the value 8.1 x 10^15 ng/m3 to units of g/cm3.

I am not sure how to do this kind of problem when the units are cubed. This is what I have so far.

(8.1 x 10^15 ng/m3) x (1 g/ 1x10^9ng) x (1m/ 100cm) = 8.1 x 10^22

well, now working through it I get 5.4x10^14

you need to cube (1m/100cm) in order to get (1m^3/[(100)^3]cm^3)

(8.1 x 10^15 ng/m3) x (1 g/ 1x10^9ng) x (1m/ 100cm)^3 = ?
